Subject: [PATCH 5/8] tools/nolibc/sys: add syscall definition for getppid()
Date: Mon, 21 Mar 2022 18:33:11 +0100 [thread overview]
Message-ID: <20220321173314.7519-6-w@1wt.eu> (raw)
In-Reply-To: <20220321173314.7519-1-w@1wt.eu>
This is essentially for completeness as it's not the most often used
in regtests.
